How to Replace Kitchen Sink Drain Basket

Updated July 20, 2017

Replacing a kitchen sink basket is a simple job, one that will save you a considerable amount of money as opposed to calling a plumber. Rarely will a sink strainer crack or become defective, but the finish on it will wear away over time and with enough use, ruining the look of your sink. Residental sink baskets are all a universal size, 1 1/2, and most local hardware stores will carry replacement baskets. As of June 2, 2010, replacement kitchen sink drain baskets cost about £3.80.

Loosen the slip nut underneath the sink with either a plumber's wrench or a slip-nut wrench. The slip nut is connected to the bottom of the strainer.

Unscrew the large brass nut underneath the sink that holds the strainer to your kitchen sink. A plumber's wrench will work best to remove this nut, since it can be adjusted to a larger size than a slip-nut wrench.

Remove the basket once the large brass locking nut is removed. It should be able to be removed by hand.

Clear away any remaining plumber's putty around the hole where the basket sat.

Place a thin layer of plumber's putty around the hole in the basin of the sink where the old basket sat.

Set the new replacement sink basket in the pre-cut hole in your sink's basin.

Place the large flat washer onto the bottom of the basket from underneath the sink and thread on the large brass locking nut, securing the basket to the sink.

Place your kitchen drain's tailpiece against the bottom of your new replacement basket and thread on the slip nut, connecting your drain to your basket. Again, you will need a plumber's wrench or a slip-nut wrench to tighten the slip nut fully.

Turn on your kitchen faucet and check for any leaks.


Try to match the finish of your kitchen basket to the finish of your faucet.
